When you combine two resistors in parallel current can flow through both resistors at the same time. Resistors are in parallel if there is a wire connecting one side of each resistor to eachother and a wire connecting the other side of each resistor to eachother.

If you apply a voltage across a resistor a certain amount of current flows.

More than 2 resistors in parallel. If you are unsure of how you get the correct answer please look below at the answer explanations section. This video is for students enrolled in the electrotechnology certificate ii career start course uee22011. Parallel circuits with more than two resistors answers and explanations here is the answer key to the problems for parallel circuits with more than two resistors.
Then the inverse of the equivalent resistance of two or more resistors connected in parallel is the algebraic sum of the inverses of the individual resistances. Most circuits have more than one component called a resistor that limits the flow of charge in the circuit. The simplest combinations of resistors are the series and parallel connections.
Resistors in parallel on the other hand result in an equivalent resistance that is always lower than every individual resistor. To calculate the total overall resistance of a number of three or more resistors connected in this way you can use the following formula. A measure of this limit on charge flow is called resistance.
If you add another resistor in parallel with the first one you have essentially opened up a new channel through which more current can flow. If the two resistances or impedances in parallel are equal and of the same value then the total or equivalent resistance r t is equal to half the value of one resistor. Although each resistor does its job to hold back the current the total resistance of two resistors in parallel is always less than the resistance of either of the resistors because the current has two pathways.
Thus the resistors act like parallel lanes of traffic each letting current through independently of what the other resistor is doing. If you think about it this makes sense. To calculate the total resistance for these three resistors in parallel.
